About the GPS

The GPS (Global Positioning System) is a worldwide
satellite-based radio navigation system.

The GPS module can calculate its location to an accuracy of
10 meters (33 feet). The accuracy depends on the number of
GPS satellites to which the GPS module is in a line of sight.
In optimal conditions, the accuracy may be within a few
meters.

If you stand still, GPS cannot detect which way you are
facing because it determines your direction as you move.

Almost all digital cartography is inaccurate and incomplete
to some extent. Never rely solely on the cartography
provided for use with this device.

The use of the GPS module requires the module and your
compatible device to be switched on. Do not switch on your
device where it may cause interference or danger.

The GPS is operated by the government of the United States,
which is solely responsible for its accuracy and
maintenance. The accuracy of location data can be affected

by adjustments to GPS satellites made by the United States
government and is subject to change with the United States
Department of Defense civil GPS policy and the Federal
Radionavigation Plan. Accuracy can also be affected by
poor satellite geometry. Availability and quality of GPS
signals may be affected by your location, buildings, natural
obstacles, and weather conditions. The GPS module should
only be used outdoors to allow reception of GPS signals.

GPS should only be used as a navigation aid. It should not
be used for precise location measurement and you should
never rely solely on location data from the GPS module for
positioning or navigation.
